- As shown in the drawings:

Referring to Figures 1 to 6 of the drawings, one improved, simple and inexpensive form of a window sash holder or control is illustrated f for use individually or in sets on window sashes for co-action with members of the window frame for 'thepurpose of holding or retaining the window sashesin set positions of adjustment within the window frame.

The window sash-holder or control as clearly illustrated in Figures -1 and 2 is preferably constructed of 'coldrolled spring steel and affords a window sash holding means which permits of the "use of a less expensive window construction wherein the ordinary sash weights, chains, cords or pulleys are not required and wherein no box frames with weight pockets are necessary. In addition to holding the Window sashes in set positions of adjustment within a window frame the improved devices also serve as a means for eliminating rattling.

The form of window control or holder as shown in Figures -1 and 2 comprises a metal body portion or strip I of a selected width and thickness. The-body portion l is shaped in the form of an arc and; is curved continuously from one end to movable contact with a surface of the window. sash, on which the opposite or upper end of the control is lockingly secured. The upper or: opposite end of the continuously curved body portion or .strip I is deflected or. bent over to form beingrztransversely racrosszztherbody strip and at.

right angles to the; side edgesthereof The lockingtflanger3 is formed atcright-wangles to a tangent; of thecurvature ofdthe :body portion The improved window retainerror control may beyused t individually or rin; sets depending upon hesize of, a :windojwvsash on which the device maybe intended for.

The inner stop strip 1 and the parting strip 8:on-1 each side of the window frame provides aguide groove or channel in which the lowersashglll is-permitted to slide. The :upper :sash;ll=is-.-permitted to slide spring fasteners may bet-secured either between one side of the sash andthe window frame stile as shown in Figures-3 and 5, or thecontrols may be -mounted between-the inner faces of the side members/I 2 and 13 of. thelower and upper sashes and respectively in backof the inner stop strip 1 and-therlower sash, and betweenthe parting strip ,-8-.'and-' thes innerrface of the side member l31-0f .thenppersash as illustrated in Figure 4.

The mounting oioneof the windowsash con-- trols orholders isvreadily accomplished byzfirstproviding a transverse 7 saw slot 1 I 4- transverselyacross, the outer side face ,l5 of -the side memberof a window sash. After the slot has been provided theedge. of the locking flange 3, ofthe holder is. positioned-in -the--opening: .of-: the slot and the body portionJ -has-.thelower. tip end Lthereof seated against the-surface l5. To se-v curethe control"inlockedhanging position on the sash, pressure is applied to thetcurved body strip, I to deflect the, same andtthereby turn, the. flangeinto a position substantially parallel totheupper andrlower walls ofttheslot l4 permit? ting the, flange 3,to ienter th zslot-as shown in dotted -lines in Figuretfi. As=the body portion. of the control is com-pressedand-theaframeemters the slot 14 the.pressure, on-the body-portion l is releasedthereby-permitting thesame to spring outwardly and at. the same time force the flange-3 to snap into a locking-position :with in the slot.

If, as shownirr Figure 3, two controls are needed for. each of thersashes, thecontrols may; be--mounted;in zthe respective-slots l4 providedrinorthe sash members. The mounting of a sash control or holder as described leaves the lower tip end 2 of the control resiliently pressed againstgthe surfac l5iof=a' window sash andspermitscslidable movement .of the tipencl on saidgsuilface -when' pressure is applied to the currvedlbody l of the control.

With the-'set of spring controls or holders engaged on zthe upper and lower window sashes in theimanner :described the .sashes may be readily mountedlinpthetwindow framebetween the respective:1zstop:1.and,zparting,strips with the body portions of .ithe. controls compressed as shown in Figure :5 i with? v.the =;outer convex surfaces of the controls innslidable contact with the inner surfaced lot was. window frame stile or jamb 5. The icontrolsvorwholders are thus supported on one side of-the-window sashes so as to resiliently hold the window sashes in position with the opposite sides-of the sashes held in contact with the surface-Bof-the opposite frame stile therebyqholdingetheg sashes in position against rat tling in the frame and furthermore serving as a means aforpermittingthe sashes to be moved upwardly and downwardly in the window frame and be retained in'any selected open positionof adjustment inwhichit may be'desired to posi- I tions the sashes;

In case it is desired to -mount the sash controlbetween the ,side membersof the window sashes and: thesash retaining or-iguide strips ofthe-sashes, it may be done as illustrated in Figurefilp byv providing rslots IS --in the inner face of the side member |3-0r .12 of therespective uppenand-lower. sashesg- With/the slots l6 provided in theselectedylocations it is only necessary to mount the sash control by engaging the flangeend-3'; thereof---in the opening of aslot and then compressthe-@curved body'portion un-v til r-the flange- 3 wsnaps into locking engagement within the slots, similar to the arrangement illus-; trated in Figure 6, when pressure 'on the body portion I of :the'controlis released.

Attention is called-to thefact that by providin-g-athe sash controls or-holders with a continuousficurve fromwne-end: tO-theother, and, havingsthe flange'3 formed 'at, right angles to a tangent line of the-curvatureof the body portion l of-the'control itis possible'to snappinglylock the. flange 3 in: 1 a receiving "slotprovided I in a windowtsash with the you-tier" and inner endiof the;flange gripping -againstropposite surfaces of the slot to resiliently hold the tip'wend 2 of the controlain' -contact with a surface pof-the sash. The flange?supportingvend-pf thexcontrol is so tightlylocked in the slotthat it is only possible towremove "-the" control :by --first compressing the 5(- sp.ring;- -body. portion vI of the control and then using asscrew dniver or other;-tool-:at-thesup! porting rend-softhet'control. to force the locking flange :3 tout Of- ED181017 into which it is engaged;

The tooth type of sash control may be mounted in position on a window slash similar to the method employed in themountingof-thetype of control illustrated in Figures 1 to 6. The toothed type of sash control, however, is also adapted for mounting on window sashes which arenot provided with receiving slots. To mount a. sash control of the tooth type on a window sash without a receiving slot, the controlis placed against a surface of the sash and the body portion I1 is then compressed into a substantially straight position as illustrated in Figure 8.- The toothed flange is then hammered 'or driven into the sash member 2| as illustrated in Figure'9. With the toothed flange engaged in position the compressed spring body portion is released permit ting the spring body by resilient action to spring outwardly into the position illustrated in Figure thereby causing the inserted toothed flange I9 to have a tendency to swing downwardly and grip into the material of the sash member 2! into a locking position to hold the control suspended in place ready to permitthe -window sash to be mounted in a window frame to permit the control to serve as a means for preventing rattling of the sash and also to permit the sash to be held or retained in a set position of adjustment within the window frame.

If desired, the toothed type of sash control may be constructed of a lighter spring steel and may be madesmaller than the 'type of control illustrated in Figures 1 and 2. When the toothed types of sash controls are of light weight material a set of eight controls is usually provided for a window, four controls for each of the window sashes.

Figures 11 and 12 illustrate another modified form of window sash control which comprises a face of the body portion 22 and at right angles to a tangent line of the curvature of the body portion is a cylindrical locking head or support which may be of solid construction or which may be hollow.

To mount the type of sash controlillustrated' in Figure 12 on a window sash, the sash'member 24 is provided with a cylindrical recess or opening 25 or if the window sash is of'the window weight control type and is already provided with the usual rope knot receiving openings, such an opening can be used forreceiving the cylindrical mounting head 25 of the sash'control 22.'

To mount the type of sash control shown in Figure 12 it is only necessary to place the control against the surface of the sash with the free end of the locking head 25 positioned at the entrance to the opening 26. The body portion 22 of the control is then compressed from the full line position shown in Figure 11 into the dotted line position to properly position the looking head 25 so that it can be inserted into the recess or opening 26 when the head 25 is substantially axially aligned with the opening. After the head 25 has been inserted the pressure on the spring body portion 22 is released thereby causing the body portion to spring outwardly into' its normal position and causing tilting of the head 25 into the full line position shown in'Figure 11 thereby causing the locking head to lockingly grip the Walls of the opening 28 to thereby hold the control locked in a suspended position on the window sash with-the lower tip end 23 resiliently held in contact with a surface of the sash to permit-movement of said free end when pressureis applied to the spring body portion 22 of the control. The sash control 1 of the type illustrated in Figures-11 and 12'when mounted in position is so securely held that it is only possible to remove the same by compressing the body portion and using a tool such as a screw driver to force the head out of the opening 26.

It will of course be understood that various details of construction may be varied through a. wide range without departing from the principles of this invention and it is, therefore, notthe purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.

I claim as my invention:
